NCT06997198
The primary goal of this study is to investigate the efficacy of deutetrabenazine treatment of TD in this previously untreated patient population. Compare movement disorder deutetrabenazine treatment response in persons with IDD to response seen in patients without IDD treated with deutetrabenazine in other treatment settings (per literature review). Compare global deutetrabenazine treatment response with validated instruments. In addition, we plan to: * Assess the safety of deutetrabenazine in the treatment of TD in persons with IDD. * Assess change in Activities of Daily Living (ADLs) in persons with IDD and TD treated with deutetrabenazine, utilizing a validated ADL instrument. * Assess change in Quality of Life (QOL) in persons with IDD and TD treated with deutetrabenazine, utilizing a validated QOL instrument. * Assess caregiver burden with a validated caregiver burden instrument. In this study, 25 participants with IDD and TD will undergo Deutetrabenazine treatment for 24 weeks. The participants will be seen for a total of 5 visits: at baseline, and at follow up visits at 3 weeks, 6 weeks, 12 weeks, and 24 weeks. This study does not include a comparison group. Therefore, researchers will compare the response of the study participants to deutetrabenazine treatment with those from a previous reported work that resulted in the FDA approval of this medication. This will be an open-label, Phase 4 study.
NCT05859698
This study will evaluate the effectiveness of valbenazine on patient- and clinician-reported outcomes assessing health-related quality of life, functioning, and treatment effect in participants with tardive dyskinesia (TD) who are receiving valbenazine for up to 24 weeks.
NCT07173920
\# Brief Summary (English Version) Tardive Dyskinesia (TD) is a hyperkinetic movement disorder induced by long-term use of dopamine receptor blockers and related drugs. Characterized by involuntary spasms or choreiform movements involving the tongue, lower face, jaw, and limbs (persisting for at least several weeks), TD causes irreversible neurological damage that persists even after discontinuing the causative drugs, significantly impairing patients' functional outcomes. rTMS is a non-invasive neuromodulation technique: time-varying currents in a coil generate magnetic fields that penetrate the scalp and skull to act on brain neurons, inducing depolarization, neural network activation, neurotransmitter release, metabolic changes, and gene expression, thereby producing physiological effects \[9\]. In recent years, rTMS has gained attention for treating movement disorders (e.g., Parkinson's disease, motor neuron disease, dystonia, essential tremor, Huntington's disease) due to its non-invasiveness, high safety, and repeatability. Studies have reported that rTMS can significantly improve motor symptoms in TD patients \[10, 11\]; however, existing research is limited by small sample sizes, conventional treatment parameters, large inter-individual variability, and unclear long-term efficacy. rTMS efficacy in TD is strongly influenced by parameters including stimulation targets, localization methods, sequences, and cycles. Optical navigation (using personalized MRI) is the most accurate and yields the best therapeutic effects, compared to manual localization or positioning caps . Regarding stimulation sequences, 1Hz and 20Hz rTMS have shown efficacy but with short-lived effects. Continuous theta-Burst Stimulation (cTBS)-a specialized rTMS mode that delivers rapid pulse trains mimicking endogenous theta-wave bursts-provides higher therapeutic doses in less time, enabling more durable efficacy and effectively reducing motor cortex excitability . Therefore, this study aims to investigate the effect of cTBS (under precise localization) on improving motor symptoms in patients with TD.

This is a A single-center, randomized, open-label, two-dose, two-period, crossover trial was conducted to evaluate the effect of food on the Pharmacokinetic characteristics and safety of oral administration of LPM3770164 sustained-release tablets 30 mg in healthy subjects.
NCT05238701
This is a single-center, randomized, double-blinded, placebo-controlled, dose escalation trial to evaluate the safety, tolerability and pharmacokinetic of LPM3770164 sustained-release tablets orally administered in healthy subjects under fasting state, providing the rationale information for subsequent clinical trials.
NCT02198794
The purpose of this study is to evaluate the long-term safety, tolerability, and efficacy of SD-809 in reducing the severity of abnormal involuntary movements of moderate to severe tardive dyskinesia. The purpose of part B is to establish the durability of effect of SD-809 following 1-week period of randomized withdrawal (SD-809 and placebo), followed by 12 weeks of maintenance with SD-809.
NCT02195700
The purpose of this study is to determine whether an investigational drug, SD-809 (deutetrabenazine), will reduce the severity of abnormal involuntary movements of tardive dyskinesia.
NCT02291861
The purpose of this study is to determine whether fixed-doses of an investigational drug, SD-809 (deutetrabenazine), will reduce the severity of abnormal involuntary movements of tardive dyskinesia.
NCT02064010
This Phase 2 study was designed to evaluate the efficacy and safety of SNC-102 in subjects with drug-induced Tardive Dyskinesia (TD). To ensure an adequate evaluation of SNC-102, a randomized, double-blind, parallel-group, placebo-controlled trial was designed. Two dosing levels of SNC-102 are employed to evaluate the proposed dosing range. A target enrollment of 90 subjects with drug-induced TD will provide sufficient data to assess the efficacy and safety profiles of SNC-102 in the target population.
NCT00917293
The primary objective is to assess the safety and effectiveness of Pyridoxal 5'-Phosphate on the reduction of expressed symptoms of tardive dyskinesia in patients with schizophrenia and schizoaffective disorders.
NCT02736955
This Phase 3b, rollover study will provide participants who completed a Phase 3 valbenazine (NBI-98854) study open-label access to valbenazine (fixed doses administered once daily) for the treatment of adults with TD until valbenazine is anticipated to be available commercially or they complete 72 weeks of treatment. This study will allow enrollment of up to 150 medically stable male and female participants with TD who previously participated in and completed the NBI-98854-1304 (Kinect 3) or NBI-98854-1402 (Kinect 4) Phase 3 study.
NCT02405091

NCT00310661
TD is a troublesome and potentially irreversible side effect associated with the use of neuroleptics. While the newer neuroleptics are improved in this regard, they all still carry the risk of TD. The present study proposes that sarizotan is a potential agent for treating neuroleptic-induced TD based on preliminary data indicating efficacy in the management of dyskinesias associated with Parkinson's disease. Its efficacy is further substantiated by pre-clinical data obtained from the vacuous chewing movement (VCM) model in rats, a model we employ ourselves in investigating the relationship between D2 occupancy and TD. The present study also examines the effects of sarizotan on cognitive function, given the association between TD and cognitive deficits.
NCT00926965
Previous researchers indicate that impaired cognitive flexibility was the primary factor distinguishing patients with from those without tardive dyskinesia (TD)1, and cognitive dysfunction correlates positively with the severity of TD2. Longitudinal data raised the possibility that the association between cognitive dysfunction and TD may reflect not organic vulnerability to but rather a state marker for this movement disorder as "tardive dementia"3. Atypical antipsychotic had been reported to alleviate the severity of TD4 and improved neurocognitive function separately5. But no researchers ever investigated the correlation of the two effects simultaneously. This randomized, single-blind and controlled study compared the effect of atypical antipsychotic on TD, neurocognitive function and associated factors for these changes.
